Install:zmysqlda October 26, 2008

download zMysqlda : http://www.zope.org/Members/adustman/Products/ZMySQLDA

download Mysql- Python : http://sourceforge.net/projects/mysql-python

First install mysql-python

unpack it.Change directory to the unpacked folder

in terminal type:PLONE_PATH/Python-2.4/bin/python setup.py install

There maybe some mysql_config path error

Like: EnvironmentError: mysql_config not found

installing the libmysqlclient15-dev package solved the “mysql_config” problem for me.

steps to use cron October 25, 2008

Help Link: Ubuntu Help

What is Cron?

Cron is a daemon used for scheduling tasks to be executed at a certain time. Each user has a crontab file, allowing them to specify actions and times that they should be executed. There is also a system crontab, allowing tasks such as log rotation and locate database updating to be done regularly.

What Is Crontab?

A crontab is a simple text file that holds a list of commands that are to be run at specified times. These commands, and their related run times, are controlled by the cron daemon and are executed in the system’s background. More information can be found by viewing the crontab’s man page.

Assume that you have command and you want to run that command at an specified time

for example I have made a sh file with this line

mkdir /home/tareqCron

saving the file naming tareqFirstCron.sh

from terminal you can test it by running to run it just go to the folder where you saved. Then type:

sh tareqFirstCron.sh

it will create a directory at /home

now delete the directory. we want to create the director at 2 am everynight

Steps to use cron :

1. open terminal

2.type crontab -e. This will open an editor where we can write crontab commands

3.the format of the line is this :

minute (0-59), hour (0-23, 0 = midnight), day (1-31), month (1-12), weekday (0-6, 0 = Sunday), command

for our example we will add this line
00 02 * * * sh /path_to_saved_sh_file/tareqFirstCron.sh

4. Now Press ctrl+O
5. press enter

Now go to sleep by running on the machine .. and wake up at 2 am at night
you will see a directory is created at /home ..
that means the command is executing at fixed time
for more example ask google ..
Thanks

Ubuntu: mounting external drives forcefully October 17, 2008

I am using both XP and ubuntu in 2 separate hard drive in the same pc. Couple of days ago i have installed XP in the secondary hard drive. I dont know why but after that I couldnt mount or see inside my drives where the xp is installed from ubuntu. Then I found help in ubuntu forum.http://ubuntuforums.org/showthread.php?t=603

I am just explaining what I have done:

opent terminal

tareq@User: sudo mount -t ntfs-3g /dev/disk/by-label/drive_name /media/a_directory/ -o force

If the directory is not created in media directory you have to create it first. with the command

tareq@User: sudo mkdir /media/a_directory

then run the above command

hope this works
